Bathroom Light and Outlet Problem
Electrical Question #1: My bathroom lights went out and now none of the lights or electrical outlets in the master bath or master bedroom are working, what could be the problem?
- Bathroom Electrical Problem
I went to my bathroom and turned on the lights that are above the mirror (no exhaust fan) The lights went out and now none of the lights or electrical outlets in the master bath or master bedroom, which is attached to master bath, are working.
- Checked the Circuit Breakers
I looked at the breakers to see if any of them were tripped and they weren’t. I turned them all of anyway and turned them back on.
- Restored the Power
Everything came back on in the bedroom and bathroom but when I turned the lights back on in the bathroom it did the same thing.
- Lost Power
Now nothing will come on.

Related Question #2:
The bathroom GFCI outlet has no power but the lights work, what is the problem?
My wife used a hair dryer. The power went out and when we reset the breaker most everything came back on. The bathroom on second floor the GFCI outlet had no power but the lights work. The upstairs bathroom has no power in the GFCI outlet or lights. I reset a third GFCI in the basement, but no change. The breaker is in the basement. I replaced both GFCI outlets on 2nd and 3rd floor with no results. An outlet in the master bedroom also is not working although on the other side of the room all outlets have power. I can’t seem to figure it out. The 2nd floor GFCI has two wires and ground. The 3rd floor has four wires and a ground.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
